  • Patent number: 8480054
    Abstract: A coupling arrangement coupling and thermally isolating a continuously variable electrical actuator rotationally coupled to and from a butterfly valve is provided. The valve may be used to modulate high temperature exhaust gas flow through an engine turbocharger. The actuator provides a continuously variable control of the valve. The coupling arrangement provides a thermal block to reduce heat transfer and vibration insulation between the actuator and the valve. The coupling arrangement generally includes a coupling shaft rotationally coupled at opposite ends to the input and output shafts by torsion spring mechanisms. The torsion spring mechanisms include yokes rotationally locking the coupling shaft to the input and output shafts. The torsion spring mechanisms allow a limited range of axial and pivotal translation between the coupling shaft and the input and output shafts and are preloaded to prevent rotational hysteresis in the valve.

  • Patent number: 8172201
    Abstract: An exhaust throttling valve (12) is provided for a vehicle. The valve includes a body structure (16, 41) having a bore (47) there-through. A shaft (28) is supported by the body structure for rotational movement. A valve member (34) is associated with the shaft such rotational movement of the shaft rotates the valve member. The valve member is disposed in the bore and is constructed and arranged to rotate between a first position substantially closing the bore and a second position at least partly opening the bore. A hard stop (56) is associated with the shaft so as to rotate therewith. First and second adjustment structures (52, 54) are constructed and arranged so that upon rotation of the shaft in one direction, the hard stop engages the first adjustment structure and upon rotation of the shaft in a direction opposite the one direction, the hard stop engages the second adjustment structure, thus limiting travel of the valve member.

  • Patent number: 8162288
    Abstract: A valve utilizes a composite two-piece housing to provide a low cost, high strength, light weight alternative to conventional metal and plastic valves adaptable for corrosive and non-corrosive environments. The valve includes a valve body defined by a first body half coupled to a second body half. A valve disk assembly is disposed between the first and second body halves. The disk assembly includes a valve disk, a valve stem and a valve seal. The disk stem is positioned within the valve disk along a central axis of the disk such that when the disk is rotated about the valve stem, the valve is opened or closed. The valve seal includes a primary portion lining an interior surface formed by the first and second body halves to engage an outer surface of the disk. The seal also includes a secondary portion disposed within and between the first and second body halves. The primary and secondary sealing portions configured to retain position within the housing and in sealing engagement with the disk.

    Abstract: A valve arrangement has an annular housing with valve seat and a two-part valve plate that is rotatable about an axis. The seat is in the form of a disk including two adjacent openings with a web between and the axis is parallel to the web. The two parts of the valve plate are next to each other with their planes parallel and offset in a perpendicular direction. They are connected to each other through one of the openings by a connection piece extending through the one opening. In a closed position for the valve, the valve plate part are respectively positioned on opposite sides of the valve seat and cover and seal the respective openings due to a seal that is between the valve plate parts and the valve seat.

  • Publication number: 20120042955
    Abstract: A valve for a plenum or pipe is disclosed. The valve includes a large butterfly valve element pivotally supported in the plenum by at least one rod. The large butterfly valve element includes an opening for accommodating a small butterfly valve element. The small butterfly valve element is coupled to the rod by a shaft. The shaft includes a recess that accommodates the small butterfly valve element but which includes a clearance between the small butterfly valve element and the shaft to permit limited rotation of the shaft before the small butterfly valve element engages at least one wall of the recess of the shaft. Thus, the combination of the shaft and the small butterfly valve element provide limited flow through the plenum. Further rotation of the shaft, however, results in rotation of the large butterfly valve element to provide greater flow through the plenum.
